Subject:     fix [2143798] Need to figure out how to do video

    Use EGLImageKHR instead of copybit directly.
    We now have the basis to use streaming YUV textures (well, in fact
    we already are). When/if we use the GPU instead of the MDP we'll
    need to make sure it supports the appropriate YUV format.

    Also make sure we compile if EGL_ANDROID_image_native_buffer is not supported
